STREET-SWEEPER.

SPECIFICATION forming part of* Letters Patent No. 548,066, dated October 15, 1895. Application filed April 4, 1895. Serial No. 544.456. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM S. KINDLE, ofl

Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a new and Improved Street-Sweeping Machine, of which the following is a full, clear, and exact description.

This invention relates to certain improvements in street-sweeping machines wherein a series of brooms is supported on and adapted to be driven from the wheels of the vehicle in such a manner as to sweep the dirt and dust obliquely across the path of the vehicle and into the boot of an elevator, also carried on and driven from the Wheeled vehicle, whereby the dirt and dust are carried upward and discharged into a collecting-chamber.

The invention consists in a sweeping-machine of this general character, presenting certain features of novelty and advantages for use over other similar machines heretofore devised, all as will be hereinafter fully set forth.

The novel features of the invention will be carefully defined in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar iigures of reference indicate corresponding parts in all the views.

Figure 1 is a sectional plan view taken in the plane of line l 1 in Fig. 2. Fig. 2 is a side elevation of the sweeper embodying my improvements. Fig. 3 is a rear end elevation of the machine constructed according to my invention, the elevatonboot being shown lin section. Fig. 4 is a sectional view taken through one of the slide-bars of the broom-frame and its slideway, and Fig. 5 is a sectional detail view showing the means for driving the elevator and gutter-broom.

In the drawings, 1 represents the frame o the sweeper, whereon are mounted the axles 2 and wheels 3, said frame having at its forward part a seat 4 for the driver of the machine, as clearly seen in Fig. 2, and being provided behind said seat with a dust-chamber 5, having an inclined false bottom 6, as will be hereinafter more fully described.

At its central part the frame 1 has secured to and depending below its under side vertical slideways aligned with each other, as seen in Figs. 1 and 3, said slideways being each formed of two parallel vertical frames 7 7, having their inner sides grooved, as clearly seen in Fig. 4, which is a detail of this part; and in said slideways are arranged to move the slides 8, having at their upper ends bearings 9 for the counter-shaft 10, the lower ends of the slides being connected, as seen in Fig. 3, with the vertically movable broom-frame. The slides 8 are thus braced at their upper parts by the counter-shaft 10 and at their lower ends by the said broomframe, as will be readily understood.

The broom-frame is composed of a series of transverse beams 11, connected together in any preferred manner, and spaced apart, as seen in Figs. 1 and 2, in such a manner as to form supports ,for the brooms 12, which are rotatively mounted between them.

Chains or other flexible connectors 13 are connected to the broom -frame at opposite sides of its opposite ends, and said chains pass over pulleys 14, journaled at suitable points on the frame 1, and extend forward toward the seat 4, being secured to a lever 15, arranged adjacent to said seat in such a way that, when desired, the broom-frame may be elevated by the driver so as to raise the brooms clear of the surface of the street, the slides 8 moving vertically in the slideways on the frame 1.

The rear axle 2 of the machine is provided at one side with a crown bevel gear-wheel16, meshing with a bevel-pinion 17, mounted on a shaft 18, journaled in a hanger 19, depending from the frame l, as seen in Fig. 2, and the shaft 18 is provided with a sprocketwheel 20, aligned with a similar sprocketwheel 21, fixed on the shaft 10 above referred to, and the movement of the shaft 18 is transmitted to the shaft 10 by means of a chain belt or similar driving connection 22, having sufficient looseness to permit of the vertical movement of said shaft 10 when the broomframe is raised to elevate the brooms l2.

The brooms 12 are each'mounted on a short shaft 23, journaled in bearings in the transverse beams 11 of the broom-frame, and on each of said shafts 23 is fixed a sprocketwheel 24, aligned with a similar Wheel 25 on IOO the shaft 10, said wheels 24 and 25 being connected by chain belts 26, as clearly shown in Figs. 1, 2, and 3.

The brooms 12 are arranged in echelon,as indicated in Fig. 1, the broom at one side of the machine being adapted to sweep the dustv and dirt into the path of that next adjacent,

as clearly seen, in such a way that :the dust?.

passes obliquely rearward across the path of the machine, and in order to sweep the dirt from the gutter a gutter-broom 27 is provided,

said broom being mounted on an inclined shaft journaled in a bracket 28, secured to the forward beam 11 of the `broom-"frame.'

The periphery of the broom .27 is inclined 4to the shaft in such a way that said periphery is parallel ito the surface to be sweptand on 1 the shaft of `said broom .27 `is arranged a sproclcet-wheel 29.,.driven by achain 30, pass- `ing over idlers .31 on the frame l, :and also. overasprocliet-.wheel 32,1iXed-on azslee-ve 2, g mounted on the rear axle 2 `of the machineat `the side of .themachine opposite .the Wheel 1G, Q

as `seen in Figs. 1 and 3, said sleeve ibeing (see Fi g. 3.) so arranged as ytoireceive thedustl anddirt acted on by ithe ylast broom d2.

An endless `apron 39 -isarranged in theecasing 36, being provided -Wit-h iflights 40, (see 1,) and the casing 36 -is inclined upward `and forward, asseen in Fig. `2.

Inorder to prevent the `chai-n Abelt 30 from y `slacking vand falli-ngoff .its sprocket-wheels` when the broom-frame `is raised, saidchain 30 runs over an idler 41, hung on a chain 42,connected to the lever l5 in :such a way `that when .the lever `15 Aisfmoved forward Yto `raise the broom-frame Atheidler 41 will be raised similari y to `keep the chain ,belt 30 taut.

In operation the broom 27 sweeps thegut-1 ter, .being driven from the .rear :axle iby gear- 1 ing at onerside .of the machine, the diirtibein-.g swept `by saidibroom out-of Uhegutter yinto.

the .path `of :the yfirst or forward broom 12, arranged just ybehind `the fbroom 27. ,Since the broom 12 .is circular and sweeps at .right angles to the curb-stone, it is'essential to set the .gutter-broomso as rto :sweep parallel to' the path .of the Amachine, in order to insure the cleaning lof the surfaces next the curb,

which are not reached by thebroom 1:2. `Said i gutter-broom 27 rbeingarranged-with its axis inclined downward toward the center `of the i machine, `causes the dirt and dust rtherefrom to be thrown outward from the curb into the path of the first broom 12. The latterbroom 12 sweeps .in adirection ltransversely of the street in such a manner as to carry the dirt and dust from between the pavingstones over into the path of the following broom 12. 1n this way the dirt is swept diagonally across the path `ofitlhe machine, being swept by the last broom 12into the elevator-boot, whence it vis carried up by the endless apron and discharged into the receptacle 5, which is provided, as above stated, with an inclined bottom Bandan outlet covered by ahinged door 43,"held in place by a catch 44. The lower part 45 of the=door 43 is arranged to project beyond the hinges 46 thereof, so that when the door is opened said lower part 45 thereof `will engage -under a projecting portion 47, rformed yon onesidewof therecepta'cle 5, where- .bythe door is held inian inclined position, as indicated .in `dotted :lines in Fig. When `in this position, the door/43 serves as a'fchute to deliver the dust from the receptacle into `a cart ort-he like.

Bythearrangementof thefbrooms 121in1independent bearings in the beams 11 `it becomes ,possible to readilyand quickly'remove adam aged broomandrepl-ace it by another witl1- out thenecessityof 'taking'the lmaehine'tothe frepairfshop.

It .is .evident that .considerablealteration `may .be madein the `machine abovedescribed, Without material departure from `the princi- .ples-.of `the invention, and iforthis 4reason `Ido .not `wis-h to .be understood .as limiting myself `to the exact .form and arrangement shown herein.
